PURPOSE: A complex dielectric is provided to ensure high dielectric constant and low dielectric loss, to enable miniaturization, light weight and high performance of electronic devices, especially, to be suitable for application to condenser, antenna, and embedded substrate. CONSTITUTION: A complex dielectric is such that high frequency dielectric ceramic powder is dispersed on a benzocyclobutene polymer. The high frequency dielectric ceramic powder is ZST(Zn0.8Sn0.2TiO4), BNT(BaNd2Ti4O12),TiO2, CaTiO3, SrTiO3, BaO-Nd2O3-TiO2, CaO-MgO-TiO2, ZnO-SnO-TiO2, and any one of ceramics in which at least one selected from the group consisting of BiO, SiO2, CuO, BN and Li2O is added to them.
